CORN-CRIB.

Application filed October 16, 1916.

To all whom it may concern Be it known that I, MARTIN B. ARM- STRONG, a citizen of the United States, residing at London, in the county of Madison and State of Ohio, have invented certain new and useful Improvements in Corn- Cribs, of which the following is a specification.

This invention relates to corn cribs and is particularly directed to an improved type of crib wherein ventilation of its contents may be effectively had to the exclusion of all moisture. A somewhat free circulation of air through a corn crib when the latter is filled, is very desirable, although it is very desirable to exclude all moisture caused from rain or snow. To this end, my invention consists in a metal crib structure provided with perforations so formed as to very efiiciently form a water shed for all moisture which may collect on the sides of the crib and t also so construct these tongues to prevent the moisture from entering the interior of the crib in its flow down the side of the same, or due to capillarity.

The preferred embodiment of my invention is shown in the accompanying sheet of.

drawings in which similar characters of reference designate corresponding parts, and in which:

Figure 1 shows a corn crib constructed in accordance with my invention,

Fig. 2 is an enlarged detail face View of one of the perforations, and,

Fig. 3 is a section taken on line 33 of Fig. 2. 7

In Fig. 1, there is shown a conventional type of corn crib constructed of a plurality of vertically arranged metallic sheets 1, all suitably connected as may be desired. Each of these sheets is provided with a series of perforations in order to permit free air circulation or ventilation. One of these perforations is shown particularly in Figs. 2 and 3.. An inspection of these figures will show that each tongue 2 is pressed outwardly from the metallic body sheet in such manner that its depending portion is substantially parallel with the body of the sheet itself. In addition, the connecting portion 3 between the depending portion of each tongue and the metal body is slightly inclined from a right angle to the Copies 01' this patent may be obtained for five cents each, by addressing the Specification of Letters Patent.

tongue and body sheet so that a water shed is provided. This connecting portion is additionallyinclined laterally as shown at 4 from a central point so that any water which may collect on the side of the crib and run down in the path of one of these tongues, this water will flow over the connecting portion 3 and be guided laterally because of the two inclines mentioned. In order to avoid the action of capillarity, the depending portion of each tongue is made substantially parallel with the sheets themselves and the distance 5 between the tongues and the sheet body is such that a globule of water, will not be retained in position. An additional feature which results from this is that the space throughout the periphery of each tongue is uniform and in this manner, a maximum degree of ventilation is afforded. Each depending portion of the tongues is also widest at its top and gradually decreases in width toward its bottom, so that water will not follow the outer edge of the same and in this manner be likely to moisten the contents of the crib itself. From the foregoing, it will be apparent that I have provided a type of ,crib structure wherein a maximum degree of ventilation is afforded and at the same time moisture is prevented from contacting with the contents of the crib, or from entering the same.

What I claim is:

A corn crib constructed-of a plurality of metallic sections, said sections being perforated by pressing out a plurality of integral tongues so that the body or depending portions of said tongues are in spaced relation and substantially parallel with the body of said sections, the joining portions between the tongues and the plate sections being slightly inclined from a right angle to each and being also inclined laterally from a central point to form a water shed, said tongues being widest at their points of connection with said sections and gradually decreasing in width to their ends.

In testimony whereof I aflix in presence of two witnesses.

MARTIN B. ARMSTRONG.
